What contemporary computing problems WCS solves?
WCS provides an entirely new approach to managing digital identities. It helps people keep track of their digital identities as distinct information cards. If a web Site accepts WCS logins, users attempting to log in to that site will see a WCS selection. By choosing a card, users also choose a digital identity that will be used to access this site. Rather than remembering a plethora of usernames and passwords, users need only recognize the card they wish to use. The identities represented by these cards are created by one or more identity providers. These identities will typically use stronger cryptographic mechanisms to allow users to prove their identity. With this provider, users can create their own identities that don't rely on passwords for authentication.
What contemporary computing problems WPF solves?
user interface
needs to display video, run animations, use 2/3D graphics, and work with different document formats. So far, all of these aspects of the user interface have been provided in different ways on Windows. For example, a developer needs to use Windows Forms to build a Windows GUI, or HTML/ASPX/Applets/JavaScript etc. to build a web interface, Windows Media Player or software such as Adobe's Flash Player for displaying video etc. The challenge for developers is to build a coherent user interface for different kinds of clients using diverse technologies isn't a simple job.
A primary goal of WPF is to address this challenge! By offering a consistent platform for these entire user interface aspects, WPF makes life simpler for developers. By providing a common foundation for desktop clients and browser clients, WPF makes it easier to build applications.
